PDS troubleshooting


New Member
I am working on an E-Z-GO PDS cart and am trying to follow the Detailed Troubleshooting Diagram in the Repair and Service Manual. In step 46 it says "Locate PIN 1- in J1, Voltage Between B- and PIN 10 Terminal'. Do I leave plug J1 plugged into the controller for these tests or can I unplug it to aid in making contant with the pins? If so Do I check at the controller or at the plug? Thanks!
